Description

This course provides a review of the operational conditions that are responsible for biological production of offensive odors in sewer systems and treatment plants and the operational measures that available to control odors. Operational conditions that are reviewed include: 1) forms of bacterial degradation that are responsible for odor production, 2) odorous compounds and precursors of odorous compounds present in wastewater, 3) forms of substrates and their impact upon the rate of odor production, 4) the odor-producing bacteria, sulfur-reducing bacteria and fermentative bacteria, and 5) operational parameters including temperature, pH, flow and others that favor offensive odor production. Changes in monitoring test values for detecting anaerobic conditions (fermentation and sulfide formation) in the sewer system and treatment plant and evaluating the success or failure of odor control measures are offered. The monitoring tests include: alkalinity, ammonia, chemical oxygen demand (COD), dissolved oxygen, hydrogen sulfide in the sewer system atmosphere, oxidation-reduction potential (ORP), pH, sulfate, sulfide, and temperature. Operational measures for odor control that are presented include biological, chemical, and physical. Biological measures presented are bioaugmentation, biofilter, maintaining an anoxic condition, and maintaining an oxic condition. Chemical measures presented are disinfection, oxidation, pH adjustment, precipitation of sulfide, and scrubbing (scrubbers), and physical measures presented are adsorption, cleaning, covers, and reduction in turbulence.

This course is sponsored by NEIWPCC in conjunction with the EPA.
